Copyright Notice

The Autors need to transfer all copyright ownership, including the copyright of the article and illustrations exclusively to the Ceylon Journal of Science. In the event that their submission is not published in the Ceylon Journal of Science, copyright ownership shall revert to the Author/s.

Peer Review Process

The submission of a manuscript will be taken to imply that the work is original, and it or a similar paper (other than an abstract) has not been concurrently submitted elsewhere for publication. The content of the manuscript is a sole responsibility of the authors.

All manuscripts are peer reviewed. This journal uses double-blind review, which means that both the reviewer and author identities are concealed from the reviewers, and vice versa, throughout the review process. Authors must provide names of three potential referees with complete postal and email addresses. However, the editors are not obliged to use the services of referees provided by authors. All manuscripts will be reviewed by two experts in the area of specialization concerned. If there are discrepancies between the comments of the two reviewers, the manuscript will be sent to a third reviewer before taking the final decision. The comments of the reviewers will be sent to the authors and the authors are expected to submit the revised version along with a point by point response to reviewer comments within three weeks of receiving the comments.

Types of Manuscripts

All manuscripts must be typed using Times New Roman, font size 12 in double space throughout Title page, Abstract, Text, References and Tables. Indicate the authority for all Latin names only at the first mention. All abbreviations should be spelt out at the first mention only.

Full length original research papers should include the following: Title page, Highlights, Graphical Abstract, Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion (Results and Discussion sections can be presented separately or together), Conclusion, Acknowledgement, Statement of Conflict of Interest, References and Appendices. The maximum number of words for a research article is limited to 10,000, including figures, tables and references. Each Table and Figure will be counted as 400 words.

Review papers should include an Abstract, an Introduction that outlines the main points, text under brief sub headings and References. Authors/s of a review paper should have carried out extensive research or study in the area concerned. Review papers should not be less than 8,000 words while not exceeding 20,000 words including figures tables and references. Each Table and Figure will be counted as 400 words. Review articles with a word count below 8,000 will be considered as Mini-Reviews. Longer manuscripts, such as Checklists, will be considered by the Editorial Board only under exceptional circumstances, based on the scientific merits.

Short communications should contain novel findings written in the form of a concise, independent report representing a significant contribution to the field of study. It should be written under the subheadings as in a research paper but should include only few key references. It may include 1-2 tables or figures and the word count should be confined to a maximum of 3,500.

Research notes briefly explain new research findings. The word count should not exceed 2,000 words.

Reviews of scientific books should be comprehensive and should not exceed 2,000 words.

Preparation of a Regular Research Paper

When submitting a regular research paper, authors should make sure to arrange the documents in the following order.

  1. Title page

Title page should be a separate document giving the Article type, Title, name(s) of authors(s) and complete postal address of the institution(s) where the work was carried out. Surname(s) of the author(s) with initials should be provided. Title should be concise, informative and typed in ‘Sentence case’ bold letters. Author affiliations should be given in separate lines. The email address, telephone number and the ORCID number of the corresponding author should also be provided.

  1. Highlights

Highlights consist of short sentences of 3 to 5 bullet points to summarize the core findings of the article. Each bullet point must contain a maximum of 85 characters.

  1. Graphical abstract

A Graphical Abstract is a pictorial and visual summary of the main findings of the article. This should be a figure that is especially designed to convey the main findings of the article and the reader should capture the content of the article at a single glance.
The Graphical Abstract will be displayed only in the online version of the article.

  1. Main manuscript

The lines and pages of the main manuscript should be numbered. The main manuscript should contain the following.

  • Title: Title should be concise, informative and typed in ‘Sentence case’ with bold letters. Authors’ names and affiliations should not be given in the main document.

  • Abstract and Keywords: Abstract for regular research papers and review papers must not be more than 300 words and for short communications not more than 150 words. It should be presented as a single paragraph and state clearly the main findings of the research and their relevance. The abstract should be followed by a list of 5 keywords. Keywords should be separated by a semicolon (;).

  • Introduction: The text should begin on a new page and arranged according to the guidelines given above. Literature in the text should be cited with only the surname(s) of the author(s) followed by year. If there are several publications by the same author(s) in the same year use a, b, c, etc. after the year. For two authors, use both names, and for three or more authors et al. should be used. The current status of the research area and the importance and relevance of the work presented and the novelty of the research findings should be highlighted.
  • Experimental/ Materials and Methods: Provide sufficient detail to allow the work to be reproduced. Methods already published should be properly cited and any relevant modifications should be clearly described.
  • Care and Use of Human and Animal Subjects: Any research that involves animals should follow established standards for the humane care and use of animals, and must specify which standards were used. When studies involve human or animal subjects, the researchers have to obtain prior ethical clearance form respective ethical clearance committees. Also, the manuscript must include (under Materials and Methods section) the names of Institutions and the Permit number of permits/ethical clearance certificates obtained from the respective Institutions/ethical clearance committees.
  • Results: Results should be clear and concise. Figures, Graphs, Photographs and Tables can be used as appropriate. These should be placed by the authors in the appropriate place in the manuscript.
  • Discussion: Here, the results should be interpreted to explore the significance of the findings, but not to repeat them. A combined Results and Discussion section is often appropriate to avoid any repetitions. Avoid extensive citations and lengthy discussions of published literature.

Experimental Methods, Results and Discussion sections can have sub-headings.

  • Conclusions: The Conclusions should stand alone as a separate section.
  • References: This journal uses APA Referencing Style.

APA in-text citation style uses the author's last name and the year of publication, for example: For direct quotations, include the page number as well, for example: (Field, 2005, p. 14). For sources such as websites and e-books that have no page numbers, use the paragraph number. More information on citing sources without pagination is given on the APA Style web page.

  • Example: a paragraph with in-text citation

‘A few researchers in the linguistics field have developed training programs designed to improve native speakers' ability to understand accented speech (Alder, 2004; Derwing et al., 2002; Thomas & Darwin, 2007). Their training techniques are based on the research described above indicating that comprehension improves with exposure to non-native speech. Derwing et al. (2002) conducted their training with students preparing to be social workers, but note that other professionals who work with non-native speakers could benefit from a similar program’.

List all references cited in the text in alphabetical order, giving the name (title) of the journal in full. List the names of all authors in the reference. The references are structured in the order: author’s surname, initials, year of publication (in parentheses), title of paper, full name of journal (in italics), volume number (bold), issue number (within brackets) and first and last page numbers.

References should be arranged in the alphabetical order according to author(s) name(s) and if there are more than one publication by the same author(s) in the same year, a, b, c, etc. should appear after the year.

DOIs of each reference must be provided where available. Book titles should be in Italics, and followed by publisher, place of publication and page numbers.
